After Effects crashes while rendering a preview (focus related?)
After Effects (CS5.5) crashes while rending a RAM preview (the composition is a 30 second, 24 fps flag waving using the card dance effect and only 800x400 pixels. 5 compositions in the project).
It renders fine when After Effects is always the tab in focus in Windows 10, but it seems that the crashes occur at some point when you switch to other Windows tabs and then back to After Effects.
An example of the crash message is below:

Below is another example of a crash with the same project, when switching back to the After Effects windows tab from another windows tab (causing I think After Effects to no longer be minimized).

So the error seems to be related to switching to other Windows tabs and then back to the "After Effects" Windows tab (so it then becomes the focus again), since just rendering the RAM preview with this project with After Effects being the the in-focus tab throughout (ie. no switching to other tabs) renders the RAM preview successfully and doesn't crash.
